SPECIFICATION forming part of Letters Patent No. 448,284, dated March 17, 1891.

Application filed May 17, 1890. Serial No. 352,147. (No model.) Patented in England April 12, 1889, No. 6,265.

To aZZ 1071,0111, it may concern! Be it known that I, THOMAS \VATTS, carriage-builder, a subject of the Queen of Great Britain, residing at High Street, Pershore, in the county of Vorcester, England, have invented certain new and useful Improvements in ShaftConnections for \Vheeled Vehicles, for which Letters Patent have been granted to me in Great Britain dated April 12, 1889, and numbered 6,265; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form partof this specification.

This invention relates to noiseless connections for the shafts of two-wheeled vehicles.

Figure 1 of the accompanying drawings represents, in side elevation, a two wheeled vehicle provided with noiselessshaft-connections constructed and arranged according to my said invention. Fig. 2 represents a transverse vertical section of the rear connection upon an enlarged scale to that of Fig. 1, while Fig. 3 also represents a transverse vertical section of the front noiseless connection. Fig. 4 is a top side plan of Fig. 2, while Fig. 5 is a top side plan of Fig. Fig.6 represents a longitudinal vertical section of the said connection upon the dotted lines A B, Fig. 3; and Fig. 7 represents a transverse vertical section upon the dotted lines 0 D, Fig. 5. The only difference between the said sections Figs. 6 and '7 is that the cushion-fulcrum or rubber block which is interposed between the inside of the metallic attachment parts and the under side of the shaft is shown distended and without the shaft pressing upon it. Fig.-

8 represents a front elevation of the said connection, and Fig. 9 a side view of it. Fig. 10 represents a section of the cushion fulcrumbox, and Fig. 11 the connection-plate of it.

(L is an open-topped fulcrunrbox or hollow casting, provided with gappcd sides a and necks a, one of which latter is directed inwardly from the inner walls of the said hollow casting, while the other is directed outwardly from the outer walls or sides. Directed vertically through the bottom of the said casting is a hole a wherethrough a connecting screw-pin 1) passes and fits, and by means of which the attachment-arm cis connected by the passin of the screw-nut b upon the wormed end of the said hanging screw.

(Z is a fulcrum or shaft-attachment plate, and e is the shaft to which the said plate is attachedly connected by bolts or strap-clips f passing through or around the said shafts, and with their wormed ends fitted with screwnuts for making the necessary attachment. This said plate d has hanging eyes or bracketbearings (Z which take upon the necks a of the box-casting a, as aforesaid.

Fitted within the hollow of the fulcrum-box or casting and extending or protruding through the open middle (Z of the attachment plate d is a rubber or other yielding block g, constituting a cushion-fulcrum, which, when in position, as in Figs. 1, 2, 3, and 6, interposes between the under sides of the shafts and the bottom and insides of the casting a.

Directed transversely through the hollow necks a of the box-casting a and the eyes (Z of the shaft-plate cl, and also the middle of the rubber block, is a pin 71, with a head 71 at one end and a screw-nut 72, at the other end, whereby the Whole of the parts of the attachment are connected together.

The parts of the connections are put together as follows: First pass the hanging screw-pin l) in position and thread the shank of itthrough the attachment-arm, then screw home the screw-nut 1) upon the screwed end of the said pin. Then pass the bracket-eyes 61 into the hollow of the box-casting a, and by a lateral sliding motion from right to left of the said shaft-plate d, the bracket-eyes d are passed onto the necks a as represented in the views. Figs. 6, 7, and 0. This done, insert the rubber block g through the middle opening (Z of the shaft-attachment plate cl into the hollow of the casting a and with the said block 1 resting at the bottom of the said casting and with its upper end protruding or standing above the top side of the plated. The said sh aft attachment parts, as aforesaid, are secured or connected together and the cushion-fulcrum retained in its placeby the passing through the said parts of the pin h, which is then secured by the nut 71 In aflixing the noiseless connection, place the under side of the shaft upon the top of the rubber block and pass the ends f 2 of the screw pins or bolts fthrough the holes or eyes d, made through d of the attachment-plate (7, when on the screwing home of the nuts f the connection is made. It will thus be seen that the upper part of the rubber block extends above the top side of the shaft-attachment plate and takes its bearin g upon the under side of the shaft in such a manner that the rubber block, on pressure being applied, is forced into the hollow of the casting and plate and through the interstices or gapse' between them, thereby keeping asunder the said metallic parts and preventing the joints from clattering. It will be also observed that the shaft-attachment plate (Z or the bearings (Pot it turn upon thebearing-necks a of the other part.

Having thus described in yin vcntion, I claim as new and desire to secure by Letters Patent 1. The combination of the hollowing casting a, having the hollow necks a a with the shaft-plate cl, provided with the bracket-eyes (1 the rubber block g, inserted in the hollow of said casting a, and the bolt L, passing through said hollow necks and said rubber blocks, substantially as described.

2. In a shaft attachment, the combination, with a 'pl'alte adapted to be secured to a shaft having a hole in the top and provided with bracket-eyes, of a hollow casting pivotally attached to said bracket by a horizontal bolt, and a rubber block fitted in the hollow casting' and projecting through the hole in the plate, substantially as shown and described.

3. In shaft attachments, the combination, with the shaft 6 and the attachment-arm c, of the hollow casting a, secured to said attachment-arm by the vertical bolt 17 and nut b the shaft-attachment plate cl, secured to the shaft and formed with an opening d in its middle part and pivotally attached to said hollow casting, the rubber block g, and the bolt 1, passing through the said block 9 and pivotally connecting the casting Ct and plate d, substantially as shown and described.

In testimony that I claim the foregoing I hat e hereunto set my hand this 29th day of March, 1890.
